Winter is the time to tie the flies for the upcoming season.Before we know it the first lakes will become ice free and then the mad scramble begins preparing equipment and tying last minute patterns.I like to use the frozen months to re-stock fly boxes and in my case it means tying a lot of chiromomid pupal patterns.There are good reasons why we use so many chironomids when fishing productive interior stillwaters.Foremost is their relative abundance in terms of both species diversity and sheer number of individuals that hatch on any given spring or summer day.In the end it comes down to having pupal patterns than match or are similar in size and colour to the most common species found in lakes that we fish.
